Preservative Treated Lumber Specification Information

AIA Lunch &
Learn Courses

Allweather Wood offers an AIA approved course around commercial and residential applications of Fire Retardant Treated Wood (FRTW). Additionally, we offer two AIA LU/HSW credit hour courses that provide insight into specifying Redwood as a sustainable building product. All three courses are available cost-free, online.

Building with Redwood Timbers

This course by Hanley Wood University provides evidence that Redwood Timbers offer a strong, durable option for building projects. It explores the use of Redwood Timbers for post and beam construction, decorative elements, and outdoor living structures such as pergolas and arbors. The course provides comparisons between Redwood and other timber options. It also provides information about Redwood’s compliance with California’s Wildland-Urban Interface (WUI) thanks to its natural resistance to fire.

This course by Ron Blank describes the features of fire retardant treated wood (FRTW), and the difference between fire resistance and flame spread. The course also lists the various types of FRTW and their specific applications. The course further explains what the model building codes require, and how FRTW is specified. Finally, the course describes how FRT wood is manufactured, tested, and certified.

Redwood: A Sustainable Building Product

This course by AEC Daily provides evidence that Redwood makes it easy to build sustainably without sacrificing quality or elegance. It also provides information on how Redwood is renewable and recyclable, and cleaner to produce than composite or plastic building products. The details of a Life Cycle Assessment (LCA) comparing redwood and plastic/composite decking options are shared, as well as information about Redwood’s Environmental Product Declaration (EPD).
